That said, even the smartest brunette can goof when making clothing choices that best complement her brown hair, from deep brunette to golden brown hair with blonde highlights. The color of your shirt or the shade of your accessories actually does have a big impact on your overall look. That’s why we enlisted celebrity color expert Jill Kirsh of Jill Kirsh Color to help us figure out which shades work best — as well as which don’t work at all — for brunettes. She explains that the hues you choose depend on whether your brown hair has a warm undertone (think browns with a visible auburn or red tint) or a cool one (ash browns and those that border on black). Once you’ve figured out which brown you’ve got (ask a friend to look at your head in the sun if you’re struggling, it’ll help show any other tones you have), tune into Kirsh’s customized tips and see which brunette celebrities know how to dress for their hair.
